View prices and availability
A tree up to 30 m tall occurring in the highlands of the Caucasus and Northern Iran at altitudes of up to 2,500 m. Young specimens have a silvery bark that turns dark grey with advancing age. Branches mostly begin low down. The bark becomes rough and takes on deep grooves: young twigs are covered in thick woolly hair. The leathery obovate leaves are 12 - 22 cm long and 5 - 14 cm wide. They are regularly lobed with 8 - 10 pairs of shallow blunt lobes. They are rough and dark green on the upper side: the underside is grey and felt-like. The acorns are grouped from 1 to 4, are approx. 2.5 cm in size and are half to two-thirds enclosed in the cupule. The cupule is covered with narrow contiguous scales. Q. macranthera is resistant to mildew.
Our trees can only be planted when they don't have any leaves. Due to the this we will start delivering again from November 2024.
